You will not validate domains in TLDs that have not been signed yet.

The .au TLD has not been signed yet, but will be signed later this
month. Signed .au domains today can only be validated because of DLV[1].
It fills the trust gap between the signed root and a dnssec signed
domain within a non-signed TLD.

Your dns will still be validating all domains with a "proper" chain of
trust, so later this month we will be able to validate .au domains
without the use of DLV.

http://stats.research.icann.org/dns/tld_report/ shows these numbers today:

532 TLDs in the root zone in total
343 TLDs are signed;
336 TLDs have trust anchors published as DS records in the root zone;
3 TLDs have trust anchors published in the ISC DLV Repository.
