Here's an example how your can calculate your cost, check the wattage on Filter, Heater & Lights.
watts/1000 = kW x hours of operation = kWh x kWh rate = cost
1000 watts/1000 = 1 kW x 45 hours of operation = 45 kWh x $.068 = $3.06
On a side note since you wanna run a 10g (which is what I use for cray's & shrimp) mine are set up with florescent small screw in bulbs that give off 40 watts, but only using 7watts to power it, saving acc to the lable right there $32. I'm sure you could find these bulbs in Australia too. Second I don't run no heater as my room temp does not drop below 70's anyways, so check what you room temp is and what you really may consider to house in there, you may not need a heater at all (or in other words you can house something in there that does not require tropical heat). Leaving you with the 24/7 running filter and its cost that you need to calculate based off its watts & whatever you kwh cost are there.
Just some thoughts to make everybody happy there
