I just use the Rain gauge and Anemometer that came with my Fine Offset (WH something from Bunnings) and it's been working great for 4 or 5 years now. But hey, if money is no object then there's the Davis and upwards.

Temp and humidity sensors, most of us have built our own.
Anyway, take a look around the forums here, there's plenty of info regarding this and where to source them.
Where about in Aussie are you?

At a place called Murgheboluc, just outside of Geelong in Victoria. I plan to use it to control my irrigation system at a small vineyard and winery so I want to build with the kids so they learn something, and use the soil moisture sensors on extra Tx's at the second stage in future. So while i'd like to control the costs its worth spending a bit more to get reliable data. If i tried to do this with a commercial system it would cost much more.

Its a big problem here Pete to get good sensors at a reasonable price. I got a Davis VP2 for $400 off a guy and just used th davis sensors and works a treat. I have been looking for another set so I can make another one for my home...my current one is up at my farm. I was/am going to make the anemometer and windvane as that is reasonably easy the temp and hunidity sensors are again easy enough but the rain gauge is another issue although I suppose you can use a FO one easily enough as they are all just tipping buckets. There is one done on the web for anemometer and windvane made from copper tube and fittings and its just a 360deg pot you can get from Element14 and the speed is just as easy with a reed switch and magnet
