Asked this week how he planned to mark the one-year anniversary of Labor's landslide election win, Premier Mark McGowan was keen to play down the day's significance.

"It is like birthdays. When you get to my age you don't celebrate birthdays too much," Mr McGowan said.

But whatever it means to the Premier and his ministers, today marks 12 months since that emphatic election victory, and it means the McGowan Government is already 25 per cent of the way through its term in office.

Labor came into power 365 days ago with a self-described "ambitious" agenda.

So how has it gone at fulfilling that in the year since?

"Metronet will deliver a world-class public transport system that is smart, affordable and achievable and will create thousands of new jobs of Western Australians." — Transport Minister Rita Saffioti

What has happened: The Labor Government sought to move quickly on its flagship election policy, convincing the Commonwealth to cough up $786 million in funding so long as studies show the Yanchep extension and Thornlie-to-Cockburn line prove viable.

But WA still has not secured a federal funding commitment for the Ellenbrook line, even though construction is supposed to begin next year, or for the Byford extension.

Money for those projects is not yet in the state budget either, but the Government insists it will all still be completed in line with pre-election commitments.

However cost estimates have already blown out by $200 million from pre-election forecasts.

'Tough on crime'

What has happened: In its first year in office, Labor passed laws making it tougher for dangerous sex offenders to be released and giving courts the power to hand methamphetamine dealers life sentences.

But the promised "no body, no parole" laws, barring convicted murderers from release unless they disclose the location of the victim's body was held up for months by the Upper House and is yet to pass.

In Labor's first few weeks in office, Corrective Services Minister Fran Logan caused a headache when he flagged the release of scores of large numbers of remand prisoners, traffic offenders, bail breachers and fine defaulters — a suggestion quickly slapped down by the Premier.

'No new taxes'

What has happened: It did not take long for this promise to look shaky and, sure enough, the Premier admitted on budget day in September he was breaking that pledge.

Big business is now paying more in payroll tax, while gold miners were spared a royalty hike because the Government could not get that measure through the Upper House.

The Government said it was sparing "mums and dads" pain by only targeting those who could afford it, but households were hit by big increases to utility bills and other charges for this year.

The Premier and Treasurer Ben Wyatt also openly speculated about introducing a levy on bank bonds and deposits, similar to a model that South Australia proposed last year.

Fixing the budget

"When last in government, WA Labor successfully built the infrastructure needed and reduced debt. We will do it again." — Ben Wyatt

What has happened: Labor promised to get the budget back in the black by 2019-20 and reduce debt over time, comparing it to a household mortgage.

But debt projections soon blew out and the surplus pledge was all but abandoned mere weeks after the election, following hits to the state's projected GST revenue.

A return to surplus in 2020-21 is now forecast, but by then net debt will have topped $42 billion.

Education funding

What has happened: In opposition, Labor blasted the Liberals and Nationals for what they described as "savage cuts" to the education sector.

But it was cuts of Labor's own making which proved highly problematic, with plans to close Schools of the Air and Moora Residential College drawing a fierce backlash.

The Schools of the Air decision was eventually reversed — along with a handful of other contentious cutbacks — but the Moora plans remain and are continuing to draw protests.

The Government promised to employ an additional 300 education assistants and has already employed one third of those.

Job creation

"Our plan has a goal of an additional 50,000 jobs and I think that is entirely achievable." — Mark McGowan

What has happened: Correlation does not necessarily imply causation, but there has been an improvement in the state's unemployment rate in the past year.

The month-to-month statistics are somewhat volatile, but WA's most recent seasonally adjusted unemployment rate was 5.7 per cent — down from 6.4 per cent in March 2017.

But in seasonally adjusted terms, the number of people in full-time work in that time has actually declined slightly.

The Government moved quickly to tighten access to certain foreign worker visas, a move it said would "put WA jobs first", and believes its planned capital works will create thousands of jobs.

Medihotels and managing health costs

"The growth and mismanagement of the health budget is unsustainable. We cannot continue on the path we are on." — Ben Wyatt

What has happened: Labor said new initiatives such as Medihotels and Urgent Care Clinics would improve treatment while helping to reducing expense growth, something it promised to do.

Now in government, Labor has set optimistic benchmarks for reining in costs while budgeting for virtually no growth in health spending in the next few years, even though expenditure has doubled over the past decade.

Actually achieving that will be another challenge, however, with the Government hoping to use a recently-released expert panel report as a blueprint to keep costs under control.

It has made a start on introducing Medihotels — facilities designed to house patients who no longer need hospital-level care but are not yet ready to go home — but it will still be three years until the first one opens.
