octopus straps

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

'transport security?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'hearty doctor tom tricks' is the wordplay.
I cannot really understand how this works, but
'tricks' could be 'traps' (I've seen this before) and 'traps' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

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