Look up ph levels for vegetables on the net. Then you will know for all vegies.

My tomato vines are full of fruit, all of it green. I've often had the problem of ending up with lots of unripe fruit at the end of the season so I was wondering it there is a sure-fire way of ripening the tomatoes on the vine before the first frosts?

My dad said he used to pull the whole plant out and hang it in a shed and the tomatoes would vine ripen then finish off on the windowsill.

Ethylene gas ripens tomatoes and some other fruit. Add a few bananas to them. Suggest you read up about how to ripen tomatoes on the internet. Read different articles. Also see if you can start your seedlings earlier in future so that they grow/ ripen earlier in future.

Also most fruit take a few weeks from being fully developed to then ripen, 3-5 weeks. Same applies to pumpkin, rockmelons, watermelons etc.

Any advice on best cool climate tomato varieties for a greenhouse in Melbourne between March and October? Thanks in advance

You are temperate, a greenhouse will raise the temperature in it. Most varieties would grow in it. Ask at your local nursery etc.

I live on the North Shore, Auckland and have done container growing for several years now, This is the third year of growing tomatoes on a large scale - predominantly determinate varieties. I source my seeds from Kings Seeds who supply a determinate variety called Sub Arctic Plenty which I have experimented with variable results. All plants raised indoors, gently hardened off then potted out into 15L tubs. I use 50/50 new compost/previously used container soil from a non-tomato pot mixed well with added slow release fertiliser and half a cup of powdered eggshell.. The top is mulched with straw and 4 marigolds to attract the bees. They also need a 5ft stake. Generally the plants like the morning and late sun and need shade from the glaring hot midday temperatures. Each year I am growing them earlier to avoid the heat of summer. The pots on the decking facing North fully exposed struggled, the pots that were shaded midday grew much better. Next year I plan to plant out in July/August and see how they get on then. They have a mild taste, personally I prefer the richer flavours of the dark toms but they are good for dehydrating. I also found that they prefer dryer soil than some of my other varieties. I liquid feed them once a week using a litre of water. Don't let them stand in trays, they need full drainage. Any run off from the trays I use on something else (the pineapple sage is very grateful). Spay every part of the plant with a brew of bicarsoda to pre-empt and control powdery mildew weekly. Please let me know if you want any other info - happy to share. Let me know how you get on.
