You would use less energy if you converted a chest freezer rather than an
upright. Everytime you open that door on your upright, all that cold air falls
out. If you have a chest freezer, you open the door and the air stays put. By
the way, this freezer conversion is used a lot by people living off the grid
and is better than a propane gas refrigerator.

Also... make sure to use a "manual defrost" unit. An automatic one
will kick in some pretty power hungry heaters (the one on my
refrigerator/freezer pulls 400 watts) for some pre-defined time,
and that number is fixed at the factory. You might only ""need",
so to speak, 2 minutes of defrost every 48 hours, but it had
to be designe for the worst case scenario.

(It's only in the past few years that we've started to see
some intelligence/feedback on defrosters).

Your fridge must be either poorly designed or its got a faulty defrost
thermostat.
Most self defrosting fridges these days will only defrost for as long
as it takes to pull the evaporator up to around 2-4C, ie until all the
ice is melted, they dont work on time.

Your Australian units are a couple of years ahead of the US...

My fridge is made in China and its a cheap nasty one but its got a
defrost thermostat.
I know as Ive had to replace it twice now.
You may be able to install one in youir fridge to save the defrost
heater running when its not needed.
They only cost a few dollars.
