European Union President Ursula von der Leyen will arrive in Sydney on Monday for a three-day visit, during which she will meet Prime Minister Anthony Albanese and become the first female foreign leader to address federal parliament.
Ms Von Der Leyen and Mr Albanese are widely expected to sign an Australia-EU free-trade agreement, ending a years-long saga defined by stalled negotiations and previously intractable disputes.
They are also expected to speak about Australia's world-first social media age ban, which some European countries are planning to emulate.
Trade Minister Don Farrell and his counterpart Maros Sefcovic will discuss the free-trade deal on Monday.
Previous negotiations have fallen apart largely due to disagreements over the agriculture sector.
The Australian side wants meat producers to be allowed to sell more of their product to the European market, a push resisted by EU negotiators who want to protect their farmers from increased competition.
Some farmers are likely to be disappointed with the level of access to European markets locked in by the deal, but the two sides have still made positive progress, a source close to the negotiations but not authorised to speak publicly told AAP.
Europe has also wanted to strip Australian farmers of the right to use geographic naming indicators like feta, parmesan and prosecco.
A compromise is likely to be reached on that dispute when the final agreement is struck.
Former Australian trade official Prudence Gordon said the drive for an agreement showed Europe and Australia were trying to push back on US President Donald Trump's overturning of traditional trade systems.
"The fact that Australia and the EU are negotiating this trade agreement now really signals their efforts to counter the chaos created by Donald Trump," the now-executive director of the Australian Centre for International Trade and Investment told AAP.
Mr Albanese has sought to frame the deal as a win for Australian exporters who could rake in an extra $10 billion annually.
It would potentially boost access for Australian businesses to a growing European market of 450 million consumers, who are eager to get their teeth into local products, he told a recent gathering of food and beverage makers.
