hi, i just had to do that to!
ive only been here for a month, so havent got my first bills ect, but i conected with origion, the lady on the phone was great, the house was already conected or something, so they had to arrange the meter reads and that was it, the first gas read wasnt available for 30 days, so she informed me our gas is free of charge untill the meter guy came out 30 days later! also receved 3 days free power for the same reason, i opted for the 25% natural power, i have not noticed a sigle doffrence with supply, but it is kinda nice knowing that im helping the envioroment that lill bit. they also have a discount for centerlink recipients, but not sure on the fortnight payments.
good luck!
