Survey covering Queensland town salaries (7)
I believe the answer is:
payroll
'survey covering queensland town salaries' is the definition.
I can't tell whether this definition defines the answer.
'survey covering queensland town' is the wordplay.
'survey' becomes 'poll' (polling is a kind of surveying).
'covering' indicates putting letters inside.
'queensland town' becomes 'ayr' (I've seen this in another clue).
'poll' enclosing 'ayr' is 'PAYROLL'.
Can you help me to learn more?
(Other definitions for payroll that I've seen before include "Total of wages" , "salaried staff" , "details workers' salaries" , "List of employees and their salaries" , "List of staff" .)
