You need at least one year continuous skilled work experience to qualify to apply as a skilled worker plus you need to make 67 points total and you need an occupation from their most wanted list or a job offer or be in Canada for a year first.
If your relatives live in AB, MB or SK, you could look into their provincial program family stream requirements and see if they can sponsor you.
One more thing, you can get a working holiday visa to go to Canada for 2 years, see
http://www.whpcanada.org.au/introduction.shtml If you can use that time to gain the necessary 1 year continuous work experience, you can apply as a skilled worker or your employer can help you apply for PR through a provincial nominee program or apply to change your work permit to a closed permit so you can reach a full 2 years of skilled work and apply for PR through CEC.
