Hey Blake, haven't fished up there for years but know there's some gravelly patchy bottom in a NE direction in 70-80m which pull stripey.
The shelfs actually not that far off (compared to out of here at Triabunna) so reckon you'd be right anywhere E or NE'ly out that way.
Tips for the drop line....
1. Make sure you have enough line
2. Have plenty of weight as the tide/current can run fairly hard in deeper water
3. Mark your drop on the GPS
4. Attach an orange buoy/or flag to your licenced buoy to as a white is hard to see with a bit of chop on
5. Don't wait too long before pulling
6. Have someone else pull it

Good luck, proka
