Jeff Clementz, managing director for PayPal Australia said "PayPal is partnering with innovative businesses like Point and Pay to help create secure and easy ways for Australian retailers to sell to customers.

"With over 50,000 merchant partners in Australia, PayPal is continuing to provide innovative solutions for our merchants to ensure they are well prepared to compete in a digital world."
David Bignold, Sales Director at West Australian Newspapers said "This is the next step in the evolution of print media.
"We're excited to be the first daily newspaper to launch a fully transactional space to help local retailers reach consumers more effectively.
