Morphology

good + authority

The meaning 'reliable or trustworthy source' is directly derivable from combining 'authority' (a recognized expert/source) with the adjective 'good' (trustworthy/competent). This is a straightforward adjective + noun composition that is cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.

Etymology

Good authority may come from the image of a respected person or office whose word people trust. Imagine an authority like a judge or elder giving information that is clearly 'good' and true, so the phrase came to mean a 'reliable source'.
