r-devel is not an ideal place to ask for this sort of advice, especially as the correct answer may be country-specific. It's unlikely that many people on this list are experts in Australian IP law.

Formally, you almost certainly need the permission of the copyright holder, who may or may not be the author. Assuming goodwill and no large sums of money at stake, permission from the author is probably pretty safe. For example, the survival package was initially circulated with permission from the author, but now is GPL with permission from the Mayo Foundation for Medical Education and Research, who are the real copyright owners of Dr Therneau's code.
