Patience, Richard, especially if you are south of Sydney, incl. Victoria where I am. The recent cooler-than-normal days have caused the plants to "baulk" - they'll only let their babies (the flowers) out to play (to start growing) in regular (and a succession of) temperatures of 20 deg. plus. Let's now about mid-December how they are going then.

Tomato and potato are the same family and carry the same deseases from one crop to the next so plant other vegies in rotation to avoid problems

In my experience the tomatoes grow from the flowers after the flowers are done so don't get rid of them. I just usually punch out some shoots and remove some foliage to help tomatoes. Leave some foliage for protection from the sun.

My tomatos started to fruit but now the plant is dying with green tomatos on the dead vines....

i would say u may be over watering them , if u dig down in the soil about 4 to 5 inches and squeeze the soil if i stays in a ball soil is ok and dose not need water.

I'm growing Red Truss and Grosse Lisse tomatoes in Adelaide. The truss plants have already flowered on plants 30cm & 40cm high. Should I remove the flowers to let plants grow taller before putting energy into fruiting?

Ive planted a variety of tomatoes this year and they all started flowering before they even got to 30 cm, I have left them and they are still growing and flowering, the early flowers have set and I have some really nice looking tomatoes already, I made my own compost and have side dressed them and I swear they have grown another 6 inches in a few days :)

Thanks Tricia - that sounds promising. That's what I'd decided to do. They certainly love compost. And who wouldn't prefer home-made? Roll on delicious tomatoes!

Your Blossom end rot could be caused by the small pot. Try a 30L minimum for a tomato of up to 1m, and 50L+ tubs for anything taller. The problem in Northern NZ (Auckland upwards) in the intense heat, humidity, and constant winds on clear days that dry the soil. The soil seesaws from dry to wet, with us trying to compensate the loss three times a day, in small pots. You'll get excellent plants, but blossom end rot, and no useful fruit. I buy seeds from Southern suppliers who have clearly defined seasons in their districts. Here in West Auckland, the sun mid-spring onward is almost too strong for tomatoes (as noted in the comment from The Shore above), and the humidity is oppressive. They are part shade plants here, and 30L is absolute minimum for varieties that suppliers claim can be grown in 18L, or less. This year I'm using no less than 54L each plant, plus grass clipping mulch. So far so good. It's the only way to maintain soil a consistent moisture.
