People searching for missing Central Australian girl Sharon Granites are grappling with tough terrain including an explosion of long grass after recent rain, as the third day of the search draws to a close.Five-year-old Sharon was last seen late Saturday night at home where recently released prisoner, Jefferson Lewis, was staying.Police allege he abducted her and believe she is still alive.Tech company Meta is railing against the federal government's plan to charge digital platforms for sharing Australian news.The proposed News Bargaining Incentive will tax Meta, Google and TikTok two-point-two-five per cent of their Australian revenue - unless they can secure a reduced levy by striking deals with news publishers.Meta - which owns Facebook and Instagram - says news organisations voluntarily post content on their platforms, and any suggestion Meta takes their content is "simply wrong".Survivors, families and community members have gathered at the Port Arthur Historic Site in Tasmania today to mark 30 years since the worst mass shooting in modern Australian history.On this day in 1996, 35 people were killed and almost two dozen were injured at the historic site, south-east of Hobart.  About 160 people gathered this afternoon at a ceremony to honour those who lost their lives and to recognise the strength of the Tasman Peninsula community.
