need some property ideas

Hi, hoping for ideas..Maybe Warnie can suggest something?

I purchased an owner occ last year and have just turned it into an investment property (and am now renting myself). I purchased (inner west Sydney). I want to buy again but have limited equity due to only owning for a year.

1) How does someone in my position with limited equity in their current investment property acquire another??? I don't want to wait 5 years for my equity to increase to buy another one then!! Are really increasing my income (servicing) or increasing my deposit the only ways when you have limited equity?
I want to purchase inner circle sydney but not likely i know, any other suburbs or maybe look at Melb or other capitals?

Any ideas/feedback would be really appreciated.
