Eight weeks to a trans-Tasman bubble is the hope for of the Australia-New Zealand leadership forum, despite New Zealand's latest Covid-19 community cases. The forum has been working for ten months on an agreement to get international travel between the two countries off the ground, with the two-way tourism trade worth more than $5 billion. Every time it seems a bubble is close there have been setbacks, new cases or divided opinions. But co-chair of the leadership forum Ann Sherry says any bubble needs to work on the basis there will be more Covid-19 cases there, and here.
