Friday marks Eid al-Fitr, the end of the month-long observance of the Islamic event marked by prayers and daily fasting.
While Ramadan is noted for its importance in spiritual reflection, Eid represents a chance for the community to celebrate with food, music and family reunions.
The Eid Show, at Bankstown Showground in southwest Sydney, is expecting thousands of attendees this weekend and has grown massively in its 17-year history.
The event is expected to be even more significant this year with the spectre of conflict in the Middle East looming over much of the Australian Muslim community.
"It means happiness, celebration - it also means hope and looking forward to something in grim times," organiser Radwan Dadoun told AAP.
There are estimated to be about a million Muslims living in Australia, according to Mehmet Ozalp, the head of the Centre of Islamic Studies at Charles Sturt University.
While many of them will choose to spend much of the weekend at celebrations like The Eid Show, mosques are also expecting a cast of thousands to mark the important religious occasion.
"We do have a big gathering (on Friday), we're going to have a congregation of four sessions," secretary of the Melbourne Grand Mosque Imran Khan Mohammed told AAP.
"We're going to have 15 to 18,000 coming from all over Melbourne."
For the mosque, Eid al-Fitr is the biggest day of the year for attendance.
Sharing food and love among families and those less fortunate forms a vital aspect of the celebration.
The homeless, single parents and others feeling financial stress benefit from the sharing of incomes and food at Eid, Mr Mohammed said.
Both mosques and shows are open to non-Muslims who want to celebrate with their friends and neighbours, with Mr Dadoun having just one piece of advice for the uninitiated.
"Come hungry and come with the beautiful smiles that you have," he said.
