It's a long drive, but about the same if you were in Sydney's western
sub's and were heading to Bondi. Except the scenery is tops! all the
way.
It's about an 1 hr 20 min drive, a bit faster if you can do Mallanganee to
Lismore in 45mins

. Actually will be heading back there to tomorrow
taking my boys to the beach. I will take a drive up to Lennox Head and
check out the Base as you have suggested. I was up there a few weeks
ago but stayed at the southern end.
Cheers,CS
