There are some state variations but generally:
Pool fencing must be 1.2 metres in height, and not made to be climbed.
Any gaps, under the fence or between parts of the formation, must be no greater than 100mm.
There should be nothing around the fence that allows an individual to climb the fence.
Gates should open outward from the pool and automatically close and self-latch.
Direct access from a house is not permitted; the house must be separated by a fence.
The self-latching gate in the fence must have the latching mechanism 1.5 meters above the ground, or be fitted with a shield. Children should not be able to open the gate from the outside.
Spas must also be fenced in some Australian states.
Do some research: A fence will be there as a permanent fixture; you’ll want to get things right. Safety come first; consider whether there will be children around, or whether you want to fence off an area for safety reasons. Are there regulations for this scenario, like a pool fence? But any circumstance has various options, and there are bound to be several that are aesthetically pleasing.
Violating safety regulations might mean the fence will not receive approval from the local council, either forcing a removal or preventing installation in the first place. Worse still, it will leave an opportunity open for accidents. Safety regulations usually have some good reason behind them.
Look at catalogues, particularly on line. With such great internet facilities available these days there’s no excuse for not looking around. Google what you’re want and copy any images you like the look of. Take note of any relevant information. Showing someone a picture of a fencing arrangement that you like is much easier than trying to describe it in words.
Always bear in mind that you can vary what you see. Some fences can be painted a different colour, or metals can be given a different finish. You might even get a design made from a different material altogether. But of course some combinations are not possible. Some metals, for example, will always have a natural, bare finish.
Cost is a consideration for everybody, but remember that this is long term investment. It is better to get is right the first time than put another fence in a few years down the road. Imagine yourself looking at a fence in a few years time and consider what you would want. Factor in the surroundings and ask yourself is this going to change.
Don’t go overboard on quotes. Big national companies can be a good source for installations, but so can small local companies. Pursue both.
Don’t install the fence yourself unless you are a DIYer and self-installation is the plan from the beginning. Remember, there are warranties and compliance issues that come with professional installation. Self installation can easily overlook these issues, and that risks fines, accidents and having to do things all over again.
