Rules covering bush poet (6)

I believe the answer is:

lawson

I'm a little stuck... Click here to teach me more about this clue!

'bush poet' is the definition.
The definition suggests a singular noun which matches the answer.

'rules covering' is the wordplay.
'rules' becomes 'laws' (laws are rules).
'covering' becomes 'on'.
'laws'+'on'='LAWSON'

Can you help me to learn more?

(Another definition for lawson that I've seen is " See 6".)

I've seen this clue in the Sydney Morning Herald.
