This is the website of Australian Radiation Protection and Nuclear Safety Agency, which is our peak body on nuclear/radiation safety.
http://www.arpansa.gov.au/News/MediaReleases/mr1_180311_0900.cfmThey are issuing regular media releases regarding the situation in Japan. This is a government agency (coincidentally, located not far from me, at an army base) and I would consider their information to be current and relevant.

ARPANSA is closely following the safety issues surrounding the Fukushima Dai-ichi site and in particular the current status of effect of hydrogen explosions, fire and aftershocks on the four reactor units and the status of spent fuel ponds at a number of the reactor units. ARPANSA notes that this event has still been rated by the Japanese Government as an INES level 4 (an accident with local consequences).
The recent earthquake and tsunami that struck Japan on Friday 11 March has caused major damage to a number of nuclear reactors on the east coast of Japan. The Japanese Government has established an evacuation zone around the affected reactors and is responding to the crisis as it evolves.
