This time last year I used twice as much gas, yet my bill today is more expensive ($ cost/day).
Hard to believe it but the costs have effectively doubled.
This winter we have rarely used the gas heating, maybe once or twice a week on the absolute coldest nights, turning it on in the evenings for ~20 minutes before my daughter goes to sleep or has a bath. Downstairs in the living area we use reverse cycle A/C for heating.
Apart from that we use the hot water and gas cooktop as normal.
My wife sleeps in the bed with my daughter now to keep her warm.
In the morning the thermometer in my room is generally 9-12C, I stay warm by sleeping in 4 layers of clothing (singlet, thermals, jumper, and flanel pyjamas) and under a 2 layer doona + blanket. And Holeproof Explorer socks.
(I'm not relating that information for sympathy, just to demonstrate how I've managed to cut my gas usage down in half).

Worth looking at removing all of your gas appliances and going all electric. Probably a pretty quick ROI.
