Obamas seen together for the first time in five months as they arrive in Sydney ... trends now

Former US President Barack Obama was seen touching down in a private jet in Sydney for a scheduled speaking tour - taking wife Michelle along for the more-than 13 hour ride for a rare public appearance.

The Obamas' excursion Down Under comes days before Barack is set to speak at the city's 'An Evening with President Obama' - where Australians willing to dole out $195 can hear about the politician's self-professed 'path to success', despite recent revelations aired by Michelle about their embattled marriage.

The event will be held in the Emerald City Tuesday, with another slated for the next day in Melbourne. Despite the occasion, the pair looked casual as they disembarked, with Michelle wearing a cardigan and jeans, and Barack sporting a beige blazer. 

The duo was accompanied by a force of security upon their arrival, and received a a personal police escort while exiting the airfield at Sydney Airport and being carted away.

Apart from some high-profile individual appearances in the media -  such as Barack being photographed on Ashton Kutcher's own private plane in LA Thursday - the outing served as the first time the couple have been spotted together in public in almost half a year. 

Known to frequently fly private after forfeiting their rights to Air Force One in 2016, the pair were previously seen casting ballots during early voting last year in Chicago, and during the formal unveiling of their official White House portraits in September.

The couple has since stayed relevant thanks to a recent a spate of interviews given by Michelle, 59, to the media - one of which saw the ex-first lady admit she 'couldn't stand' her husband for nearly ten years starting soon after Barack's first term.

Speaking to Black news station Revolt TV last December while peddling her new book, Michelle revealed the extent of that hatred - and how it boiled over while the couple's kids, Malia, 24, and Sasha, 21, were growing up.

'People think I'm being catty by saying this – it's like, there were 10 years where I couldn't stand my husband,' she told a round-table forum of the phenomenon, which surfaced when the kids were around 10 and 7, respectively.  

'For 10 years while we're trying to build our careers and, you know, worrying about school and who's doing what and what, I was like, 'Ugh, this isn't even,'' she said of the strains she felt at the time on her now three-decade marriage.

'Ten years – we've been married 30,' she recalled, speaking to a panel that included Destiny Child star Kelly Rowland and Beyoncé's mother Tina Knowles-Lawson.

'I would take 10 bad years over 30 - it's just how you look at it,' she said of how she and her husband eventually circumvented their marriage woes with time, while seemingly decrying other couples with less patience.

'And people give up … [saying], 'Five years – I can't take it,'' she said.
