For example, if you want to search for the #LockTheGate campaign, search --> hansard Australia "Lock The Gate"

• Putting the quotation marks around your campaign name so that the search engine doesn't show results for just "lock" or "the gate"

  
  

  
  

  Then, a quick way to look if the source is relevant is by control + f "Lock the gate" to see excerpts that concern your campaign.

If you want to be even more specific, think about

• which state or territory you want to focus on (e.g. "Queensland)

• which specific legislation/ policies you want to talk about

• if there is an important figure in your campaign, try searching their name instead of the campaign's name -- this might bring some new sources :]
