After mine broke at work last week, needed a new one. Never usually see these for less than $60 at the hardware stores, so it's quite a bargain.
Seems to be available at most stores that I checked with a few exceptions.
Cheapest one at Bunnings is $69.
Heavy duty version also available for $29 https://www.masters.com.au/product/900024207/olsent-havy-dut…
Latest RCBO Protection
10A/240V/2400W maximum load
RCBO safety switch/overload protection
4 individually switched outlets
Cord storage area around base
Fully complies with AS/NZS 3190
High visibility orange case

That one (product code MAS_900024206 )is out of stock in WA, however this one appears exactly the same but $29
