FOR IMMEDIATE RELEASE

Debt Financing Update

Sundance Energy Australia Limited (ASX:SEA) is pleased to announce that the Company has closed the previously announced debt refinancing with Morgan Stanley Bank, N.A. and Morgan Stanley Capital Group Inc. (together "Morgan Stanley"). The transaction retires fully Sundance's current Revolving Credit Facility and Second Lien Term Loan to provide

$250 million of new committed debt capacity. The new facility includes (i) a $300 million

Senior Secured Revolving Credit Facility ("RBL") with $75 million available at closing of which $25 million was drawn at closing and (ii) a $175 million Senior Term Loan Facility (the "Term Loan") of which $125 million was drawn at closing and $50 million will be in the form of an undrawn contingent commitment. The RBL has a 5 year term and bears interest at LIBOR plus 2 to 3 percent depending on the amount drawn. The Term Loan has a 5 ½ year term and bears interest at LIBOR plus 7 percent with a 1 percent LIBOR floor. Both the RBL and Term loan are secured by a first lien on substantially all of the Company's assets and have customary financial covenants.

Pro forma for the closing of the transaction, the Company estimates its total liquidity position to be approximately $63 million as of March 31, 2015, including cash on balance sheet and availability under the RBL but excluding the $50 million undrawn contingent commitment. In conjunction with the transaction, the Company intends to increase the hedged volumes of oil and gas production. This attractive financing with a Tier 1 bank demonstrates the quality of our assets and provides us with adequate flexibility to manage the business.

GMP Securities, LLC acted as the sole Financial and Structuring Advisor to Sundance as part of the transaction.
