Attempts to foster public interest as camping is out (9)

I believe the answer is:

campaigns

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

'attempts to foster public interest' is the definition.
I can't judge whether this definition defines the answer.

'as camping is out' is the wordplay.
'is out' indicates an anagram (out can mean wrong or inaccurate).
'as'+'camping'='ascamping'
'ascamping' with letters rearranged gives 'CAMPAIGNS'.

Can you help me to learn more?

(Other definitions for campaigns that I've seen before include "political events" , "pushes" .)

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