Its part of the Act that its reviewed after two years.
You do have a say thru your association same as us, members of the public can have a say too check out the Safecom web site.
A review is a good idea, if you have ever read the act, its got a lot of grey areas. Check out the SES section and compare it with SAMFS & SACFS, you will see what I mean. Also some parts of the Act would sit better as a Regulation under the Act, which means when its modified it does not have to go to Parliament everytime. cheers
