The sad part is how expensive it is (I’m in Australia too). Seems up front like a cheaper alternative to pavers but both the moulded plastic and the soft plastic that fans out versions are a solid $40-$45/sqm AUD.

Can buy brick pavers for that and you still have to purchase the pebbles to go in it…

brick pavers need a tamped gravel base, then bedding sand, and then polymeric sand to lock them together. the cost of install is not just the cost of pavers. and installation is something that requires enough skill that it's possible to do it wrong. depending on how much weight you plan to drive over it, you might also need to pour a concrete base for them.

geogrid is orders of magnitude easier and quicker to install.

Pavers for $40-45 - are going to be pretty unattractive grey concrete (well, cement) ones, right?

Even Bunnings (albeit marketplace) has 100mm geogrid for $20 / square metre.

Most local vendors have 'call us for pricing', but I've found a few others in the $10-20 range. Obviously, yes, in-fill on top of that - say $250 a cube depending on your tastes, so add $12-25 per square metre.

As per sibling comment - with some fabric underneath, and a modest amount of ground prep, installation of this stuff sounds fast and easy.
