Early voting for Australia's federal election officially commenced Tuesday, with polling stations opening nationwide ahead of the May 3 election date. The Australian Broadcasting Corporation reports election authorities anticipate approximately half of all votes will be cast during this pre-poll period.

Campaign Developments:

• Prime Minister Anthony Albanese (center-left) and Opposition Leader Peter Dutton (conservative) will face off in tonight's televised debate - the third of the campaign, with a fourth scheduled for Sunday

• Both major parties have recently escalated campaign promises, unveiling billion-dollar policy packages

• Recent Newspoll shows Albanese's Labor Party leading Dutton's Coalition by 4 points after preference allocations

Key Context:

• Dutton's popularity has waned following his push for Trump-inspired policies, including:
  • Public service job cuts
  • Mandated office returns for government workers

• Albanese's Labor currently holds a slim majority (78 of 151 seats)

• Analysts predict a close contest amid high early voter turnout

Election Mechanics:

• Australia's compulsory preferential voting system in effect

• 150 House seats at stake (reduced from 151 due to redistribution)

• Early voting available for those unable to vote May 3
