Tomatoes not growing

It has been such a mild summer here so far that the tomatoes have not even grown yet! I need my tomatoes, home grown are so much better than bought ones in the shop. We even had a fire going last week and they say it is summer in Australia - might have to rethink that one and makes me wonder what Winter is going to be like this year. We also need some more rain, things have dried out oh so much. Australia is one country where the weather is always changing. You can really have all four seasons in one week.
