We have a 2013 Hilux and have had the breathers on since new and never had an issue, we regularly make water crossings some deeper than others.
I am no expert, but it might be worth checking if you need the breathers in Victoria as you probably wouldn't have the same level of issues down there that would justify the purchase; unless you're wading in water for any length of time.
Righto, by full set you mean both diffs, transmission and transfer case?and yeah I might not need them around home often, although around Gippsland and the High Country there are some pretty deep crossings in winter with the rain and snow melt, but with mates around Australia and work taking me everywhere, I'll definitely be heading up north more than a few times a year as well.
