It seems to be some sort of DNS issue, but I don't know exactly what. An HTTP
connection to www.anz.com.au takes about 45 seconds to establish, regardless
of the browser. E.g.
time telnet www.anz.com.au 80
Connected to www.anz.com.
Escape character is '^]'.
A DNS query, however, responds almost immediately:
time dig www.anz.com.au
;; QUESTION SECTION:
;www.anz.com.au. IN A
;; ANSWER SECTION:
www.anz.com.au. 9798 IN CNAME www.anz.com.
www.anz.com. 1 IN A 220.127.116.11
www.anz.com. 1 IN A 18.104.22.168
And an HTTP connection by IP number instead of by name responds almost
immediately, also. I see no packets coming from them (e.g. IDENT queries)
that would account for the delay. One of their IP numbers (22.214.171.124) has
no PTR record, but I don't think that has anything to do with it.

Could be an issue with the FreeBSD resolver. It's happened in the past, but I
thought that was all cleared up now. I don't know if "dig" uses the native
resolver or implements one of its own. I suspect the latter.
