SQL & PL/SQL :: Inserting Values For All Column Names In Trigger

I am working on convertion of triggers from SQL SERVER to Oracle. I got them converted using a tool. But not sure how to correct the below trigger which uses '*' in sql server.

Code in SQL SERVER :-

CREATE TRIGGER INSERT_AUDIT ON T_AUDIT
FOR INSERT AS
INSERT INTO T_AUDIT_LOG
SELECT 'INSERT','AFTER', CURRENT_TIMESTAMP, NULL,*
FROM INSERTED

Converted into Oracle:-

CREATE OR REPLACE TRIGGER INSERT_AUDIT
BEFORE INSERT
ON T_AUDIT
FOR EACH ROW
INSERT INTO T_AUDIT_LOG
VALUES ( 'INSERT', 'AFTER', SYSTIMESTAMP, NULL, * );

END;

how can I remove the *. I tried replacing the * with the rest column names prefixing with :NEW.

the last 3 columns when are c_data1,c_data2,c_data3 as :-
INSERT INTO T_AUDIT_LOG
VALUES ( 'INSERT', 'AFTER',SYSTIMESTAMP NULL, :NEW.c_data1,:NEW.c_data2,:NEW.c_data3);
But this gives error:-
PLS-00049: bad bind variable 'NEW.C_DATA1'
PLS-00049: bad bind variable 'NEW.C_DATA2'
PLS-00049: bad bind variable 'NEW.C_DATA3'

how can I convert this code.
