Although this unit is taken (1 bedroom) you could contact the rental agent and tell them you want something similar in the area of your choice? This is reputable agency so you should get some assistance.
You could transfer a bond deposit to them if you're keen, though I don't know what the stipulations are regarding having to look at the apartment first? Though it's Sydney, so money talks.
No worries. Good luck.
