Geoscience Australia's web page for getting the magnetic variation on a specified date at a given lat/long. eg Trinity Beach

Requested: Latitude -16o 47' 00", Longitude 145o 42' 00", Elevation 0 km, Date 2012/11/13
Calculated: Latitude -16.7833o, Longitude +145.7000o, Elevation 0.00 km, Epoch 2012.8661

Components of the Magnetic Field

D, the magnetic declination (sometimes called the magnetic variation), is the angle between the horizontal component of the magnetic field and true north. It is positive when the compass points east of true north, and negative when the compass points west of true north. Declination is given in degrees and its annual change is in degrees per year.
