TransACT provide broadband and phone services in and around the ACT, Australia. Mostly to residential customers:

[transact.com.au...]

Whilst a the odd occasional single IP might be used for nefarious purposes (as can happen in any reputable company offering hosting), the vast majority is benign.

I also consider Funnelback to be benign, and if I felt it offered no benefit to my websites, I'd ban it via UA, not IP. Especially not a range that could lock out a swag of potential visitors.

YMMV.
