If you hit that link, you'll see this:
General Information on Election Financing

o Campaign returns of candidates in an election, leadership contestants, nomination contestants and financial transaction returns of registered electoral district associations and registered political parties
* Contributions and Expenses at a Federal Election or By-election: Candidates and Registered Parties – backgrounder
