5. Tiahleigh Palmer's murderer sentenced to life
In May 2018, Rick Thorburn was sentenced to life in prison over the murder of his 12-year-old foster daughter Tiahleigh Palmer in 2015.
Thorburn killed Palmer and dumped her body in a Gold Coast river after he discovered his son Trent had sexually abused Tiahleigh and also feared she might be pregnant. The murder went unsolved for 10 months, but after an anonymous tip prompted listening devices to be installed in the Thorburn home, recordings revealed Thorburn telling his family to "stick to the story". The whole family was arrested in September 2016.
Thorburn was the last family member to be sentenced in relation to Tiahleigh's murder and will be eligible for parole in 2036. Trent pleaded guilty to charges of incest and perjury and was released in January 2018 after spending 16 months in prison. Thorburn's wife Julene and other son Joshua also spent time behind bars after pleading guilty to perjury and perverting the course of justice.

7. Critically ill children transferred from Nauru to Australia
Angry over the indefinite detention of refugees and asylum seekers on Nauru and Manus Island, advocates spent 2018 taking the Australian government to court.
Multiple lawsuits filed in the Federal Court saw children removed from Nauru on the basis of needing urgent medical treatment in Australia. Many children had attempted suicide or self harm, and others were diagnosed with resignation syndrome, a rare psychological illness in which they withdraw from the world and cease to eat, drink, and talk.
Some removals were ordered by the courts and others were agreed to by the government after court action was filed. The ongoing lawsuits came against a backdrop of growing fury over the children detained on the Pacific island, and a prominent campaign led by doctors, lawyers and advocates to get everyone out of indefinite detention.
In May, there were 137 children detained on Nauru; on Dec. 7 prime minister Scott Morrison said there were fewer than 10.

In September, broadcaster Alan Jones and two radio stations broke the unenviable record of facing Australia's largest ever defamation payout.
Jones, Sydney's 2GB and Brisbane's 4BC were ordered to pay $3.4 million to four brothers from the Wagner family after Jones defamed them on air by suggesting they were responsible for 12 deaths during the 2011 Grantham floods, following the collapse of the wall of a quarry owned by the Wagner family.
Justice Peter Flanagan found that Jones' conduct was "unjustifiable" and that he had acted with a desire to injure the reputations of the Wagners.

Former archbishop of Adelaide Philip Wilson was acquitted in December of covering up child sex abuse when a judge quashed his conviction.

But he appealed the decision and judge Roy Ellis found in his favour, ruling there was in fact reasonable doubt that Wilson had committed the crime.
