Is that a Cockney accent? It sounds a little Australian to me. One of my closest friends is a Cockney but he sounds nothing like the gecko. On the other hand, my friend is kinda old and his Cockney is much more old-fashioned. Wonderful to hear him say, “Ya dossey cow!”
I think they intend him to be Cockney. Word forms like
“innit?” are definitely cockney. Then phrases like “wha’ ever else streyeks yor fancy” But you’re right they do like to confuse aussies accents with cockney. The East Enders show helped to keep it alive. See my other post with a link to the Fast Show “We’re Cockneys” pretty funny stuff there.
Liked your comment about old letters, true in our family— if we read them as they’re written with our current accent it gives a pretty good rendition.
