Was a bit windy and the colours were quite flat, so had a bit of a play in lightroom. Unsure of what they are called, had a quick look in google and didn't have much joy.
It they are only tiny ( about 1cm across) they may be a tiny native daisy which can come in white, pale pink or even pale blue tones. I'm sorry but I don't have my plant book with me to give you a possible scientific name. This is a lovely image of them.
@Weezilou Asters came up a fair bit in the google search, but I think @robz is on the money here.
@robz I was thinking that they were some type of native daisy as well. The are tiny probably only 1 cm across. Loveliest purpley blue to them.
