(Reuters) -The global aircraft leasing arm of Australia's Macquarie Group said on Tuesday it has purchased 30 Boeing 737-8 aircraft, marking its second direct order with Boeing.

The company did not disclose any financial details of the deal in the statement.

Separately, Boeing said that the purchase was booked in July as "unidentified" on its Orders and Deliveries website.

The purchase brings Macquarie AirFinance's 737 MAX order book to 70, with the aircraft scheduled for delivery through to 2032, the firm added.

"By expanding our fleet with these state-of-the-art aircraft, we are reinforcing our commitment to providing sustainable and cost-effective solutions to our partners," said Eamonn Bane, CEO of Macquarie AirFinance.

Macquarie AirFinance and Boeing did not immediately respond to Reuters requests for comments.
