Help - I won an orchid in a raffle!!!!

[chook]

I won an orchid in a raffle. The label says "Maytime'. It was in flower when I got it - and gorgeous. It has survived inside at my daughter's house for six months and I have now brought it home. I'd love to have it flower under my care. I'm an 'ordinary' gardener, live in Australia with summer temps over 40 C/winter temps below zero and would appreciate answers to the following:
....indoor or outdoor (I'm guessing indoors)
....water how often
....it won't like wet roots, will it
....red spider mite, when to treat
....special fertiliser
Hope you can help.
They are such a breathtakingly beautiful plant. We visited an orchid show and I thought I'd do the right thing and buy a raffle ticket
