Another Australian diplomat is being sent home as the Fiji military government hits out after the cancellation of the Melanesian Spearhead Group.
Australia's acting high commissioner Sarah Roberts has been told she will be served with a "persona non grata" and will be given 24 hours to leave the country.
Foreign Minister Stephen Smith says the decision to expel Roberts was "unjustified and unjustifiable".
But he says Fiji's remaining senior diplomat in Australia will not be dismissed in retaliation.
"If I responded in kind, that would see Fiji unrepresented in Australia and would effectively see the end of our formal diplomatic contact."
The BBC says it's unclear why Fiji took the latest action, but Smith said Suva was angry with Canberra because of disagreements over scheduled meetings of various Pacific island political groups.
The Stuff website in New Zealand has been more direct saying it was because Australia would not support the summit meeting of the Melanesian Spearhead Group (MSG).
New Zealand has also refused to support the meeting but it is not known whether Suva will act again against Wellington.
Bainimarama had touted the MSG summit later this month as a counter-point to the Pacific Forum 16-nation summit that has suspended Fiji's membership.
The MSG takes in the Melanesian nations of Papua New Guinea, the Solomon Islands, Vanuatu and the Melanesian political party in the French territory of New Caledonia.
Bainimarama had persuaded several Polynesian nations to attend the summit and claimed it was to counter the domination of Australia and New Zealand in the forum.
But he got a rude awakening from the prime minister of Samoa, Sailele Tuilaepa Malielegaoi, who penned the following letter:
Dear Interim Prime Minister
re: Invitation to be an Observer at the Melanesian Spearhead Group Meeting – July 21-23, 2010
I refer to your letter of 24 May, 2010 faxed to my office on 6 July with your invitation to attend the MSG Meeting of Leaders in Suva, Fiji.
I was given to understand that the advice to the Ministerial Contact Group meeting in Auckland at the end of May, by your representative, was that only those non-MSG countries that had indicated a wish to attend would be invited. I had not expressed any such wish. On the contrary, when the media asked me sometime ago if I would attend if invited, my reply was no.
I am afraid that nothing has happened since that has given me any reason to reconsider my decision.
Now that your invitation has come, I wish to let you know that as one of the long serving and senior members of the Pacific Islands Forum, I am afraid that I do not, in all sincerity, feel that it would be right for me to accept your invitation.
An invitation for non-MSG Pacific leaders to an MSG Leaders Meeting has never been made before to my knowledge. Samoa certainly has not been invited previously.
That non-MSG countries were not invited was a state of affairs that made sense to me, as the MSG members would wish to use their meeting to discuss issues pertinent to them. Very importantly the MSG also brought any issues to the Pacific Islands Forum that the MSG felt was of wider interest to the Forum. This is the relationship and practice which has enabled sub-regional groups and the Pacific Islands Forum to exist side by side and work together as well as allowed the latter to retain primary status in our Pacific region.
For the MSG meeting about to be hosted in Fiji, I would imagine that the MSG members, as done in the past, will bring to the attention of the Pacific Islands Forum any issues from its meeting that they feel the Forum should also consider.
The above said, I want to take this opportunity to again continue to plead and encourage you to quickly return Fiji to Parliamentary democracy and allow the people of Fiji their freedoms and rights.
