Data released by Google appears to show ‘lockdown fatigue’ in Australia.

The tech giant says travel data shows Australians and US residents beginning to move about more in their cities, while people in Japan and Singapore have increased their time at home.

In Australia, visits to transit, workplaces and entertainment venues plunged 80 per cent in mid-April, but are now rebounding as the rate of new cases slows.

Google's US data traffic to workplaces was down 48 per cent from the baseline by last Friday, meaning more people are going to work than during a 56 per cent drop on April 10.

Epidemiologists in the US predicted there would be fatigue with lockdowns as weather warms and people protest shelter-in-place orders.

Singapore has seen success in rigorous contact tracing and surveillance, but the nation-state went into lockdown on April 7 after outbreaks in migrant worker dormitories.

Retail and park visits in Singapore fell about 25 per cent in the first weekend of April and were down about 70 per cent by April's final weekend.

Workplace visits, down just 20 per cent at the beginning of April, were at nearly 70 per cent by last week.

Traffic to sites in Tokyo halved after Japan's emergency declaration and has remained at that level.
