With regard to teacher supply, the Government's been working to increase participation in initial teacher education. Of course, there are long time frames involved here between when someone signs up for an initial teacher education programme to when they actually make it into the classroom. We also know that, again, in an economic downturn when there are fewer employment opportunities, we see participation in those sorts of programmes going up. So I'm feeling optimistic about that. We know that in terms of existing teacher supply, we do have enough teachers in the system now to meet the formulaic entitlement for schools up and down the country. What we don't have enough teachers necessarily to meet are the additional teachers that schools employ over entitlement, and, of course, the COVID-19 situation does have an impact on that, because in some cases they'll be paying for those teachers from external revenue sources like international students, and so we may see some reallocation of the existing teaching workforce as a result of those changes. Of course, I do want to acknowledge that for those teachers, there'll be some bumpy times ahead.
