Internet / Broadband in Samford Valley

I am thinking to move into acreage property in the Samford Valley area (Camp Mountain, Highvale, Samford Valley), but it is critical that I have reliable internet connectivity for work. Currently where I live I get reliable ADSL2+ which is sufficient for my needs. Could anyone provide me with their experience of broadband internet in this area?

If the internet is indeed poor, are there any rural areas of a similar nature that are provided with a good internet service?

Thanks.
