Need help on expenses in Sydney for an Indian Family

Hello friends living in Sydney,
I have a job offer based out of Sydney. I am not too sure of expenses and want opinion from residents of Sydney if below are correct estimates and would be enough for Indian family of three (including 2.5 yr old daughter). As I will be coming on 457 visa i will have to bear cost of day care and insurance (my PR is on the way).
Below are the expenses i could figure out, can anyone please confirm. I need to decide by this weekend itself.

All expenses in AUD:

House rent - 1700/month (my office is in Macquarie Park - which suburbs are recommended that are well connected, have decent schools/day care/basic facilities in mind as i am really scared on rent part in Sydney )
Groceries- 1200 / month (we are vegetarian family, fond of fruits and tea teetotaler)
Utilities (gas, electricity (Air Con, Geyser, Chimney, Hot Plate), Water)- 200 / month
Travel within city from suburb to Macquarie Park for work- 250/month (for self and spouse)
Day care (3 days a week) - 1200/month (i.e. @100 dollars per day, 3 days a week hence 3 *4 = 12, 12 *100 = 1200 dollars)
Health insurance - 200/month
Cable TV/broadband - 200/month
Mobile- 100 (2 connections)
Gym - 200/month(for 2 members)
Swimming Pool Entry for child per visit - 10/visit

Can anyone correct or confirm if something wrong.
Any other miscellaneous expenses need to consider before taking decision of moving for good to Sydney?

Appreciate your help.
