The Dogtra EF3500 Invisible Dog Fence kit is an expandable containment solution suitable for dogs weighing from 7kg, offering the capacity to secure up to 40 acres of property with the purchase of additional wire. The system features a fully waterproof (IPX7) and rechargeable collar unit that utilizes a vibration-only warning signal prior to delivering any static correction, which can be manually adjusted across 8 distinct stimulation levels to match the dog's temperament.

Supported by a simple 4-step containment setup and backed by a 2-year Australian local warranty through DogMaster, the kit includes a strict safety directive that the collar must never be left on the dog for more than 8 to 12 hours a day to avoid the risk of pressure necrosis.

VIC
https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/pocta-act-1986/electronic-collars/cats-and-dogs/antibark-and-remote-training-collars-for-dogs
Under the Prevention of Cruelty to Animals Regulations 2019, electronic shock collars (excluding citronella or non-shock GPS collars) are strictly restricted to dogs and cats. For dogs, anti-bark and remote training collars must meet specific technical standards and can only be used on animals over six months old that have been deemed physically and temperamentally suitable by a veterinarian. Furthermore, these collars must not be worn for more than 12 hours in any 24-hour period, must be introduced via an approved training program, and can only be applied by, or under the direct written supervision of, a qualified dog trainer or veterinary practitioner, with mandatory reviews conducted within the first six months and annually thereafter. 

NSW - WE ARE UNABLE TO SELL TRAINING COLLARS INTO NSW
https://legislation.nsw.gov.au/view/whole/html/inforce/current/act-1979-200#sec.16
In New South Wales, the use, possession, and sale of electronic shock collars are strictly prohibited under Section 16 of the Prevention of Cruelty to Animals Act 1979, with details publicly available on the official NSW Legislation website and through the NSW Department of Primary Industries (DPI). While the state enforces a total ban on remote training and anti-bark shock collars, carrying severe penalties for individuals and corporations, the law provides a single narrow exception for electronic containment systems. These invisible boundary systems are only permitted if they are paired with a secure, physical perimeter fence that stands at least 1.5 metres high. 

QLD
https://www.legislation.qld.gov.au/view/whole/html/current/act-2001-064
In Queensland, electronic shock collars, including remote training, anti-bark, and containment systems, remain entirely legal to buy, own, and use, as the state does not enforce specific restrictions or an outright ban. Instead, their use is governed broadly by the Animal Care and Protection Act 2001 (QLD), which outlines a strict "duty of care" requiring owners to protect animals from unreasonable pain or distress. While the Queensland Government recently updated this legislation to officially ban pronged collars, electronic shock collars remain permitted as long as they are used responsibly and do not cause injuries or severe suffering that would legally qualify as animal cruelty. 

NT

In the Northern Territory, the use of electronic collars is regulated under the Animal Protection Act (recently updated to the Animal Protection and Related Legislation Amendment Act 2025).

While Section 30 of the Act enforces a general ban on using electrical devices on animals, the accompanying regulations list specific exceptions. Under these exceptions, it is legal to use bark collars and electronic containment systems on dogs; however, remote-controlled training collars are strictly prohibited for standard consumer use. Any permitted use of an electronic collar must still align with a pet owner's legal "minimum level of care" responsibilities, meaning the device cannot be used in a manner that causes injury or severe distress, which would constitute an offense under the territory's updated animal cruelty laws.

WA
https://www.legislation.wa.gov.au/legislation/statutes.nsf/main_mrtitle_1138_homepage.html
In Western Australia, the use, possession, and sale of electronic shock training collars, anti-bark collars, and invisible fence containment systems are legal for dogs under a specific regulatory exemption. While the Animal Welfare Act 2002 broadly categorizes electric shock equipment as inhumane, Regulation 7 of the Animal Welfare (General) Regulations 2003 provides a legal defense for their use on dogs, provided the devices are applied in accordance with generally accepted methods of usage. This means that while owners do not require a formal permit or veterinary prescription to use them, the collars must be used responsibly; any misuse that results in severe physical distress or injury remains subject to prosecution under the state's broader animal cruelty laws. 

SA - WE ARE UNABLE TO SELL TRAINING & CONTAINMENT COLLARS INTO SA
https://www.legislation.sa.gov.au/lz?path=/c/a/animal%20welfare%20act%201985
In South Australia, electronic shock collars, including remote trainers, anti-bark collars, and invisible containment fences, are completely illegal to possess, sell, or use under Section 15 of the Animal Welfare Act 1985 (SA). The state enforces a blanket prohibition with no consumer exemptions, meaning that attaching an electric shock device to an animal for containment or behavioral modification is a prosecutable offense, regardless of whether the device is turned on. Pet owners in SA must rely on humane, non-electronic alternatives like positive reinforcement or vibration-only training tools. 

TAS
https://www.legislation.tas.gov.au/view/html/inforce/current/act-1993-063
In Tasmania, electronic shock collars are currently legal to purchase, possess, and use, as the state does not have an outright ban or specific standalone restrictions targeting them. Instead, they fall under the broad regulations of the Animal Welfare Act 1993, which requires that any device used on an animal must not cause unjustifiable pain, distress, or suffering. While the use of shock collars is permitted for general behavioral training and containment, a recent Tasmanian Government position paper on dog welfare outlined proposals to only allow devices that emit an audible or vibratory warning signal before a shock is delivered. 

ACT - WE ARE UNABLE TO SELL TRAINING & CONTAINMENT COLLARS INTO ACT
https://www.legislation.act.gov.au/a/1992-45/
In the Australian Capital Territory, electronic shock collars are entirely illegal under Section 13 of the Animal Welfare Act 1992 (ACT), which strictly prohibits placing any electric shock device on an animal or administering a shock. The territory maintains a complete blanket ban with zero consumer exemptions, meaning that remote training collars, automatic anti-bark collars, and invisible boundary containment fences are all unlawful to use. Pet owners in the ACT must utilize humane, non-electronic training methods, as using any shock-based equipment faces strict prosecution under the territory's animal welfare laws.

The perfect coffee mug warmer!
Color: Wood
If you need a coffee cup warmer for your desk or work-station, this is it! I've been using almost daily for several weeks now and zero complaints thus far. As with many-a-reviewer, the problem I was trying to solve is my coffee going cold long before I was done with it, leading to repeated microwave rewarm sessions. After reading through numerous reviews, articles on the matter, and forum postings, I settled on this product. My requirements: - I did not want to use a specialized cup - I did not want to have to find "flat-bottom" cups, I wanted to use any cup in my cupboard - I wanted the coffee to stay hot, not just warm - I needed auto-off, since I surely would forget to turn it off - Idiot-proof controls This product's description seemed to check all the boxes, and it delivered! I've been using for several weeks and it's been perfect. It works with my regular ceramic coffee mugs, and on high setting, keeps my coffee pretty hot (130F). All my ceramic mugs are concave bottom - look at picture in my review - so that's why it only gets that hot on High. A flat-bottom cup may only need Medium setting since it would have more contact area for heat transfer. The faux-wood trim makes it look sorta classy, and although it is large, it doesn't look absurd on my desk, and I'd rather it be bigger than my cup, rather than too small. And I imagine I could use it to keep soup or other food warm on my desk, since I also take forever to finish food when I do eat at my desk. The faux-wood trim does not get hot-to-touch, so it also prevents burns from accidental touch. The surface is, of course, very hot but no little kids or cats in our house, so that wasn't a concern for me. I'm glad I went with this 36W option, even though some articles I read indicated this was overkill. As mentioned above, I imagine I need the higher wattage heating element because I use regular concave-bottom coffee mugs. I have it plugged into surge protector that powers my tower PC and 4 UHD 27" monitors, and I haven't tripped anything yet. 36W is even less than what a fast-charging laptop charger would pull, so this doesn't seem excessive for a workstation. FOOD SAFETY WARNING: As a former research lab assistant that grew bacterial cultures as one of my duties, I'd like to remind people to keep in mind that the danger zone for bacterial growth is ~40F to 140F, especially with dairy creamers. To test temperatures, I used a ceramic concave-bottom mug (starbucks mug in picture) and a metallic flat-bottom mug (green mug in picture). Here are the liquid temperatures I measured for this warmer: - Ceramic convex-bottom mug, Warmer on High: 130F - Metallic flat-bottom mug, Warmer on High: 175F - Metallic flat-bottom mug, Warmer on Med: 150F As you can see, the concave-bottom makes a significant difference in heat transfer, and thus the temperature of the liquid. Use common sense on how long you leave your coffee on the warmer. Coffee at 130F is probably fine for a couple hours, but if you're gonna be leaving it all day, you'll want it to be at 140F+, so use a flat-bottom cup. The metallic one I have got real hot to the touch, including handle and lip of cup, even at Medium, so you'll probably want to use a ceramic one.

My favorite desk item
Color: Wood
I love my coffee but it must be hot-every sip! I'd get up at work so often to go reheat my coffee in the nuker & don'tlike the microwave AND a hater coworker even commented to me that she noticed "how much I get up from my desk" so I thought, they gotta be making coffee hot plates for desktops these days & boom, they do!! I like the wood finish, right my aesthetic alley. The plate has 3 settings; high, medium & low. Even has an auto shutoff after..idk how many hours so built in safety. I've even put my ceramic cup of soup on there to keep it warm while I work through lunch a couple times & it worked for my soup on the high setting. Coffee goes to medium when I first get in since it cools on the car ride over & then down to low once it's hot again. Will be getting one for the home office here soon.

Mug warmer
Color: Wood
This is a well made mug warmer, heats up quickly and convenient to use. The heat ratio is high making it easy to select the level of heat one wants to have to enjoy their coffee, tea, hot chocolate, etc. The only default I have with this product is how to turn on the warmer. It's convenient but if something is sitting next to the warmer, the warmer turns on too easily. I would recommend the manufacturer use some type of switch to turn on, adjust and turn off the warmer due to the chances of heating something up that was not intentional!

Simple and very useful
Color: White
Right out of the box it works just as expected, gets perfectly hot. Even with a small cup, my coffee typically cooks to quickly for my taste. Jumping up to give it a pop in the microwave gets old fast. Problem solved. For already hot coffee, the low is enough to keep it sippable. I'm pretty sure I could hear a can of soup from room temp on the high setting. I do hope it is doable because this is a perfect hot plate.
