Interesting question. I live at Sorrento on the Mornington Peninsula,
Victoria and I don't have records of Striated Thornbills within 3km of
the Bass Strait coast. All my records of Striated Thornbills near the
sea are at locations on Western Port Bay and not Bass Strait - near a
bay and not a coast.
Also the habitats are quite different as the eucalypt woodland of the
Western Port Bay sites is not present along the Bass Strait coast.

Subject: Striated Thornbill distribution
Hi all
I'm hoping that some of you can help me out. I'm interested in
distribution constraints on Striated Thornbills. I've a number of
theories to test, but in the first instance, I'm interested in
distribution alone.
Striated Thornbills are quite abundant in forests/woodlands on the
ranges and "coast" from South Australia to south east Queensland, but
how close to the coast are they found? Does anybody on the list have
records of Striated Thornbills within: 3 kilometres of the coast? 2
kms of the coast? 1 km of the coast? or less than 1 km from the coast?
I'm looking for signs that these birds carve out a life for
themselves very close to the coast. I cannot recall one time that I
have seen even a lone, stray, Striated Thornbill within 3 or 4 kms of
the sea.
I got several family groups raising fledgelings yesterday at
Ingleside on the northern beaches of Sydney. This would be 4.5 kms
from the coast as the thornbill flys, but it is also quite elevated,
being on a high plateau, so conditions were not as "coastal" as down
on the northern peninsula. On the south side of Sydney, near Kirrawee/
Grays Point, I've also got several families building nests and
another nearby group of families each raising fledglings. The site is
fairly close to water, but is not "on the coast". i.e. it's quite
elevated compared to Cronulla or Bundeena.
Breeding observations would be considered the most robust evidence,
regular sightings would be considered next most compelling and single
birds or one-off observations not nearly so exciting.
