You get no choice in what technology the NBN uses to hook your house up. You can confirm your current scheduled technology at the NBN site. What date does the site say yours is arriving?
Assuming its FTTN then you may need to wire your own internal copper. NBNCo will wire a lead in to your home up to the front of your house (There may be a nominal charge for this ~$300, but in most cases its free). On the day the technician may be happy to run the cable a bit further into the house if its not too hard. Its up to them when you ask.
FWIW Optus will shut your HFC connection down around 3 months after the NBN is available in your street (so get onto deciding a ISP to supply the NBN to you - That can be Optus or any other ISP)
Note that FTTN is indeed the worst of the NBN technologies but that doesn't mean its all bad. Its just there is a fair variability of what speeds it can supply and you won't know what your hom is until you get hooked up. 75%+ of homes will get 50Mbps+ but 25% of homes might struggle to get 50Mbps early on.)
