European Union regulators have hit Google with a record $6.85 billion antitrust fine for using its Android mobile operating system to squeeze out rivals.

It represents just over two weeks of revenue for Google parent Alphabet and would scarcely dent its cash reserves of almost $140 billion. But it could add to a brewing trade war between Brussels and Washington.

Google said it would appeal the fine. "Android has created more choice for everyone, not less.

Jakarta police have shot 52 alleged petty criminals, killing 11, in a two-week blitz aimed at making the city presentable ahead of next month's Asian Games.

Since the start of the month, officers have arrested 320 people, shooting dozens of them in the legs.

Some of those wounded have been paraded before the media, their legs still bandaged, in an apparent warning to any criminals considering targeting tourists.

Jakarta's police chief says the fatal shootings will be reviewed but he has made no apology for the "firm measures”.

Senator Penny Wong called for Australia to start their own Pacific Islands infrastructure fund, following moves by the New Zealand government and an increase of interest by the US and Japan.

"I welcome these announcements as important steps to addressing the deficit in infrastructure investment in the region," Senator Wong said.

A local council on the south-west fringe of Sydney is lobbying the State Government to limit the number of cats non-breeders can own in New South Wales.

Wollondilly councillor Simon Landow is leading the push to impose the statewide cat cap, which he believes will create "an equal playing field between dogs and cats".

Mr Landow said while the limit would ultimately be determined by the Government, he believed owners should have no more than six felines unless they're registered breeders.

A long term study of the Great Barrier Reef has shown the recovery times of the reef overall has fallen over the eighteen year period studied.

The study, published in Science Advances, used eighteen years of data to conclude that the ability of most reefs to recover following massive events had fallen by, on average, 84 per cent between 1992 to 2010.

An animal rescue group is urging people to take pets they can no longer care for directly to rescue groups or shelters.

In June, six-month-old Trixie was offered up "free to a good home" on social media by her Bundaberg owners who were no longer able to care for her.

About a fortnight later she was picked up by a council animal control team as a stray with multiple lacerations to her face.

An attempt to deploy a new submarine for Spain's navy has run aground again, after it emerged it cannot fit in its dock, Spanish media reports.

The S-80 boat was redesigned at great expense after an earlier mistake meant it had problems floating, and it was lengthened to correct the issue.

A Spanish newspaper now reports that after the changes, the docks at Cartagena can no longer fit the vessel. The cost for each vessel has almost doubled.

Germany, Hungary, and other European countries have called for asylum seekers who initially landed in Greece to be returned to the Mediterranean country.

Late last month, Greek Prime Minister Alexis Tsipras said a deal was reached to return refugees and migrants from Germany to Greece and Spain.

However, Kyriakos Giaglis, Greece's country director for the Danish Refugee Council, explained that previous attempts to return asylum seekers to Greece were "never really" implemented.

Trackless trams are predicted to take over city streets in the near future, with the technology currently being trialed in China.

The trams runs on “virtual rails”, instead of having to concrete rails into the road to allow the street cars to run, with steel wheels being replaced by rubber tyres.

"A light rail system that sometimes, like in Sydney's case, cost $120 million per kilometre, we think could be done for $5 million per kilometre," Professor Peter Newman said.
