First of all the transmission might appear to be an automatic, but VW use a DSG transmission which is basically a manual transmission with 2x clutches and 2x gearsets and a computerised brain which does all of the work for you.
What you are feeling is more than likely the clutches shuddering as they are very well known for, especially so in the particular gearbox your Polo uses. The clutches overheat and burn out in heavy traffic and then start to shudder and slip.
Take it to either an independent VW specialist mechanic or VW themselves. Dont go to a regular mechanic as they wont have a clue what they are doing and will send the gearbox to a specialist anyway.
Where in Sydney are you? Might be able to send you to a good independent VW specialist mechanic based off what part of the city you live in.
