Jenny, have a look at their website here:-

There are suitable binoculars for a reasonable price - something like 9x63 (9 magnification, 63mm of aperture). You'll also need a tripod - a good camera tripod (say Velbon) for about $120 will do. You'll also need an adapter to mount the binoculars on a tripod - Bintel can advise. Binoculars can also be used during the day for looking at all sorts of things.
But maybe a telescope would be better. She will see more and with greater detail. I honestly think that a reflector mounted on a dobsonian mount (A "dobsonian" or a "dob") is easiest to use. Bintel sell a Skywatcher 6" Dobsonian - that is, a 6 inch diameter primary mirror (the aperture). This telescope isn't the sort of thing one would use during the day for looking at birds, etc. I know there are cheaper telescopes on tripods and equatorial monts, but you cannot go past getting the biggest aperture you can afford.
Now you can get cheaper prices on binoculars and telescopes, but then you need to be buying from elsewhere - probably on-line with shipping. I thought you might prefer to buy from a shop where you can see what you buy and have people that you can go back to with any queries or worries.
The problem with Glen Waverley is the light pollution. Many of the observing targets talked about on this site need darker skies to see. But the Moon, the planets, many star clusters can all be seen - enough to get excited about. Many people can spend all their time happily observing the Moon as it goes through its phases over the month.
I have no personal experience of astroclubs in the Glen Waverley area - can others advise? This is an intersting hobby. Many do it quite solo, others really like having larger groups around. Depends on your daughter's (?) personality. If you did get a scope or binoculars, I'm sure one of us would be happy to drop by and get her started. I'll be happy to help.
