The billionaire co-founder of Chinese e-commerce giant Alibaba appeared in Australia this month, according to media reports.
Ma was seen with an Australian family, the connection to which could date back more than four decades.
Ma is in Australia now, domestic media yicai.com reported on Sunday, citing an anonymous source.
Some social media users ran into Ma recently in a hotel in Melbourne and took a picture showing that Ma was browsing his mobile phone while drinking Coke.
Since completely withdrawing from Alibaba's board of directors, Ma's whereabouts has been garnering media attention.
Ma left Alibaba's board of directors after stepping down as an executive chairman in 2019, though he continues as a life-long member of the Alibaba Partnership.
