welcome from Western Australia. take you time don't rush, build up your fabrics, if you have something in mind work out your colours and blends buy a bit extra just in case you goof, (I have plenty of times), the tutorials are great and there are lots of links to look at,
I think one of the most important things is to learn how to sew a straight line, (easier said than done for some people) then learn how to sew a 1/4 inch seam as that is the most common.
after that. just go for it, I have been asked to teach a young friend to sew and they don't even have a sewing machine. the last one they had went rusty from lack of use,
