What is the percentage change in the total lease liabilities from 2018 to 2019?
{"Lease liabilities -- Current": {"2019 $000": 2569, "2018 $000": 2599}, "Lease liabilities -- Non-current": {"2019 $000": 6773, "2018 $000": 5934}, "Lease liabilities -- ": {"2019 $000": 9342, "2018 $000": 8533}}
total_lease_liabilities_2019 = df["Lease liabilities -- "]["2019 $000"]
total_lease_liabilities_2018 = df["Lease liabilities -- "]["2018 $000"]
