Thanks Chris,
My pier has a 250mm round top plate and a 250mm square bottom plate. The post is 110mm square and steel is 6mm all round except for the gusset which is 10mm steel.
The footing will be 40x40cm and 60cm in depth (approx 10 bags of premix concrete). I will cast 12mm threaded rod into the footing and bolt them into the four corners of the square bottom plate.
Hope that helps.
Bo
