i no the bubble wrap is good insulation for the winter months, but will it help in the summer heat or will it make my greenhouse hotter.
Will bubble wrap on my greenhouse protect from the heat?

No skin will cool the greenhouse interior.
Skip the bubble wrap.
I use Solexx fabric on my greenhouses. Read up on it. Good stuff, but pricey.

thanx for your reply, that stuff looks awesome, i searched the net there is no Solexx in australia well not that i couldt find. ill keep looking but i also thought of an idea of having 2 greenhouse skin layers about 10cm apart and runnign aircon through that layer so the heat doesnt reach the plants.

If you want to see nearly a whole grow in greenhouses, as well as outdoors, read my grow thread. It's long, but includes some tutorials and a description of my greenhouses' design and why I've built them with certain features.
I live in the California Central Valley, which amounts to irrigated desert. Temperatures can reach 115 degrees, most years, here.
Green house temperatures have reached 130 degrees with no damage.
The reason is strong ventilation.
This lets the plants cool themselves with evaporation while benefitting from an increased metabolic rate, from the heat.
In OZ you'll want your intake vents at the bottom of the East, North and West, and the exhaust vents on the South side at the top.
There are other fabrics similar to Solexx.
You can also use clear fiberglass panels.
Insulation really shouldn't be necessary.
Solexx's design is more for light distribution than insulation.
Two layers of clear plastic will work, but degrades rapidly. Usually within a year or two. I'm assuming inside and outside the framework.

cheers mate thanx for all your help, im actually going through it now but i got dial up so the pictures are killing me. another question I had is im going to run extraction fans connected to cabron filter for the smell. how many times per minute or hour would the air have to replenish?

My system replaces the air a little more than once a minute. This keeps the plants cool, and keeps CO2 levels as high as ground level, outdoors.(CO2 is heavier than air).
Putting a carbon filter on a greenhouse exhaust is probably a waste of money.
A better route might be a quiet, powerful fan, pointed straight up.
Greenhouse exhaust is warmer than surrounding air, and should continue to rise above the noses of your neighbors.
My nearest neighbor, downwind, to the North is about 200 ft away.
