Debt is multi-currency but breakdown of currencies is not known. There is a natural hedge ( partial) given 75% of future earnings are GBP. Can't recall hearing of any currencing hedging strategy beyond the natural.

GBP is holding up much better than $AUD approx 7% decline to $US over year compared to $AUD decline greater than 25%

Most of debt is for UK purchase and W/C so presumably most of debt is in GBP. That is fine UK earnings will fund the debt. But of course we will be earning far greater than debt repayments so balance is favourable FX as pointed out earlier.
