Welcome to the Quilting Board Lozza! My sister & brother-in-law recently moved back to California from Queensland (Macleay Island). I think we may have at least driven thru' Toowoomba when I was there on holiday! What a lovely place to be if you've a love for flowers :D
It sounds like you have a full plate, working and going to school for nursing. Be sure to take a little time for quilting now & again. And we'd love to see some of your work too!
You might also like to check out the University of British Columbia's Botanical Garden website - I subscribe to their "Botany Photo of the Day". They're usually lovely, sometimes creepy, but always have lots of info - http://www.ubcbotanicalgarden.org/potd/ . Best of all, it's free! lol
