Thanks everyone for all the posts, looks like plastic is the way to
go, but I was asking about best value - Im on a budget of about $2000.
Want to get the biggest tanks I can get delivered for that. No pump, I
live on a slope so will gravity feed driplines.

Dynaplas seem to have a store on ebay!
delivery syd is only $95

looking at this

They seem to be joining 3 tanks via polypipe to make up 4350l of
storage. Splitting storage into 3 tanks must be easier to
install and handle but wondering if there is a disadvantage.

I must admit that I wouldn't be keen on the polypipe connections. The
upside is that they are visually reasonably good looking.

I must also be getting old and tight because for the amount you have
allowed, we got a 9,000 ltr concrete tank not so many years ago.

I have been planning to make up at least one of what the Poms would call
"water butts" from used 220 ltr olive containers and chemical containers
like these:

I even have the olive barrels which IIRC correctly cost me $20 each, and the
taps which have a gasket on either side and a screww that tightens up and
forms a seal on each side of the barrel wall. All I have to do is drill a
hole. Just haven't got around to finding my "round tuit" tool.
