Accurate alignment when i cant see south, or east

Polar aligning, for me is a pain, i cant see south so i cant use my polar scope, and i cant see east.

Can someone correct me if i'm wrong here, but this is what i have for accurate drift aligning steps in southern hemisphere.

here are my notes, does anyone have any other tips? have i got anything back to front, as i have compiled these notes by reversing other directions etc

1. Level Mount
2. Compass Align mount to S (-11Deg offset for me) and angle to 28.3deg for Latitude

3. Point to star low (20 degrees) on the WEST horizon within 5deg of the celestial equator (slightly north)..
If the star drifts SOUTH my angle is set too low so angle it up (drift NORTH = too high)

4. Point straight up to meridian and C equator (straight up and slightly north)
If star drifts NORTH, axis is too far EAST - so rotate mount further West (clockwise) if drift = SOUTH then EAST(counterclockwise)

5.repeat

i am getting CLOSE, i can do about 30 sec at 400mm, or 1Min at 100mm but i cant quite nail it, and i can't see the SCP to check, i'm wondering if i'm missing a trick, and almost everything i read is relating to Polaris, or using the polar finder etc
