I currently work within the Pond Industry and thought you all might be interested in the laws relating to fencing of Pools and or Ponds
Below is an extract from the Queensland Building Act 1975 that is still current today
Q. What is the definition of a swimming pool?
A. Schedule 2 of the Building Act 1975 defines a swimming pool as an excavation
or structure that is:
• capable of being filled with water to a depth of 300mm or more;
• capable of being used for swimming, bathing, wading, paddling or other
human aquatic activities;
• used, designed, manufactured or adapted for the purposes mentioned
above, despite its current use.
Swimming pools include spa pools, spa tubs or similar (whether portable or
fixed) and wading pools (other than a portable wading pool).
It does not include:
• a fish pond or pool (used, designed, manufactured or adapted for this
• a dam or tank (used, designed, manufactured or adapted for aquaculture,
marine research or water storage);
• a watercourse;
• a portable wading pool
I should also add that at the end of it all Common Sense Prevails so if you do have little ones fence it to be safe.
