We’ve rounded up all the latest stories from Australia and around the world – so you don’t have to go searching.

1. Lydia Ko becomes the youngest ever world number one golfer.

Seventeen-year-old Lydia Ko has become the youngest ever golfer to take out the Australian Open.

Earlier this month, the New Zealand national also became the youngest world number one golfer in history.

Ko is also the youngest golfer to win a professional event, taking out the women’s NSW Open when she was just 14.

According to the ABC, Ko loves playing in Australia.

“I’ve always played well in Australia, so it’s always cool coming back here,” she said.

2. This Girl Can campaign targets the gender gap in sport.

By ABC.

An English advertising campaign designed to encourage girls and women to play sport has gone viral, attracting 16 million views on Facebook and YouTube.

This Girl Can features a squadron of joyful, jumping and perspiring women, and aims to address the huge disparity between female and male participation in sport.

England ranks third in Europe in terms of male participation, and ranks 19th for female participation.

“So there is the most enormous gender gap, and if we could just crack that it would make a massive difference to the lives of women and girls,” Sport England chief executive Jennie Price said.

The advertising campaign also takes on the hefty issue of how women do not fear physical activity, but rather the judgment of others.

“And [the campaign] is edgy and it is disruptive but it’s basically celebrating all those women and girls who have decided, ‘Damn it. I don’t care what people think about me. I’m going to get out there and do it’,” Ms Price said.

She said she did not expect the extent to which the videos would go viral, saying the campaign seemed to have “really struck a chord with people”.

“I think the message we’re trying to get across here, which is that if you have this thought in your head when you think about sport and exercise, that ‘I’m not fit enough. I look dreadful in those clothes. I don’t really know the rules anymore’, that that is completely normal,” she said.

She said the Australian director of the television ad, Kim Gehrig, was “absolutely fundamental” to the creation of the campaign.

“When we talked to her about the research, she got it instantly, what we were trying to do,” she said.

“So I think we’ve tapped into something here which is genuinely universal.”

Ms Price is unapologetic about using the word “girl” for the campaign.

She said it was to target teenagers and to take the word as a youthful crown for older women.

3. Children to be returned to offshore detention centres, meanwhile government investigating 44 cases of sexual assault.

Children in Australian detention centres are to be returned to Nauru.

Fairfax Media reports the number of children being detained on Nauru is expected to increase by about 50 per cent.

That figure reflects plans for children who were initially transferred from Nauru to Australia for medical reasons to be returned back to the island’s detention centre, Senate estimates heard today.

Sky News has reported there are currently 126 minors in onshore detention, 68 of which were moved to Australia temporarily to receive medical treatment.

There are currently 116 children on Nauru, with 68 more children waiting to return there following their medical treatment in Australia.

Meanwhile, police are investigating 44 sexual assault allegations involving children in Australian detention.

Recently, the Human Rights Commission released a damning report into the treatment of children in detention centres — stating that assault and mental illness were of vital concern.

4. Passenger vessel sinks, killing 66 people.

A ferry has sunk in a Bangladesh river, killing at least 66 people.

The overcrowded ferry collided with a cargo vessel on the Padma river and sank within minutes.

More than half of the bodies retrieved so far were woman and children, according to regional police official Harun-ur Rashid.

As reported by the ABC, an 18-year-old girl broke down in tears as rescue workers brought the bodies of three members of her family into the terminal — including her one-month-old baby sister.

“They took a meal at my home and then left for home [on the ferry],” the girl who gave her name only as Akhi said.

“A few hours later they are all gone,” she said while staring at the baby.

Rescuers are still searching for missing passengers, but do not know the total number of people onboard. According to survivors the ferry was carrying between 70 and 150 people.

5. Eight teachers have been implicated on child sexual abuse charges at elite Sydney boy’s school.

By ABC.

Elite Sydney boys’ school Knox Grammar has apologised for failing to protect its students from sexual abuse by teachers, members of what one student described as a paedophile ring.

The Royal Commission into the Institutional Responses to Child Sexual Abuse has heard that a group of teachers at the school molested boys as young as six between 1970 to 2003, but that senior administrators of the school did nothing.

Five former teachers have been convicted of numerous offences and much of the abuse happened in the school’s boarding houses.

Three other former teachers have also been implicated but have not faced criminal proceedings.

The commission has heard documents recording abuse complaints have mysteriously disappeared from the school’s records.

Geoffrey Watson SC, acting for Knox Grammar, told the hearing the Uniting Church-run school in Sydney’s north failed to protect students.

“The school humbly and sincerely apologises for its failure,” he said.

“It apologises to all of those students who are damaged by these events.

“It apologises to the parents of those students and to the other members of their families.”

“Mr Watson said the school welcomed the royal commission and that “it’s important the truth emerges.

“There’s no excuse,” he said.

“The school owed a primary responsibility to those students and to those parents to keep them safe from this sort of thing.”

6. Andrew Chan and Myuran Sukumaran release a statement from death row in Bali.

Bali Nine inmates Andrew Chan and Myuran Sukumaran have released a formal statement via their brothers.

As reported by news.com.au, the pair are thankful to the Indonesian government and people, and remind the public to be respectful of the nation and its customs.

Michael Chan and Chintu Sukumaran addressed media outside Kerobokan prison today:

“Our brothers are very grateful for the support and kindness shown to them by so many people and we are amazed at the strength and resilience during this stressful time.”

As they reflect on their past they are also thankful to the Indonesian Government, the prison officials and many volunteers that have allowed them to create a wholistic rehabilitation program that is now the envy of most prisons worldwide.

We see and hear many prisoners doing courses go onto jobs and better lives. Our brothers’ great wish is for the President to allow them to continue this help, to rebuild the lives of many more Indonesians for many more years to come.

Myu and Andrew love Indonesia, they have a great respect for the Indonesian people and its culture and it was through the support of the Indonesian justice system that they were able to help set up many programs that have helped a lot of Indonesians and has also helped better themselves and they are very grateful for that.

And I just want to remind everyone to remain respectful at this time and thank you for all your support.”

The statement comes in the midst of tension between the Australian and Indonesian governments, in response to Prime Minister Tony Abbott’s comments regarding the Tsunami aid provided by Australia.
