The federal Coalition says the NBN is taking too long to roll out and it costs too much.

Mayo MP Jamie Briggs says on top of those concerns, it’s not prioritising the areas with the worst broadband.

He says many towns in the Hills, Fleurieu and on KI have poor broadband access.

The Coalition yesterday launched a nationwide survey on broadband speeds to help, what it says, prioritise broadband deficient areas.

The survey is available online via www.fasterbroadband.com.au
