What Mr Cornwell has said is very good. Plenty of Automatic Weather
Stations (AWS) about from "budget" to "how deep is your pocket". B-)

The major gotchas are probably the computer interface/software. Does
the AWS talk to a computer directly or do you need another
"logging/interface" box? Is data format and/or the software
proprietary?

Are you wanting lots of sensors dotted about your "extensive orchards
and gardens", which combined with "Australia" conjures up images of
100's of acres and distances well beyond your average wireless
sensor. Or would a single set at or near the house suffice?
